Audio-visual schemes for the automotive likeness processor
Today’s very admired in the automotive enjoyable recital procedure, on advancing the scope for of video playback, motor vehicle enjoyable recital procedure is the solitary audio from the conventional procedure into a video, customer manual and integrated navigation system. Video show clearly, for instance the amount assortment from high-end 3-inch to 7 inch range. Shows that the content of knowledge usually embraces analog (such as computer disc competitor or digital broadcasting and television) and digital knowledge (such as multimedia customer interface and fascinating wallpaper). Figure 1 presenting a motor vehicle audio system. Solomon Systech Image Processor chip-SSD1922 aspects to get concurrently these needs.
Video and image content can be processed and SSD1922 interface through digital screen at Delta or stripe type TFT display. If the video source to meet BT656/601, systems design would be a reduction of the video decoder and more easy.
JPEG images can be preserved in the SD interface SD / MMC card. SD small discern can be read from the JPEG record, after decoding interface through the liquefied crystal show clearly to the LCD video screen
JPEG encoder obstruct from video source (camera or computer disc input) to receive images. Ability to deal with its hardware, you can promptly show clearly any JPEG image. SSD1922 sustains dynamic JPEG format. SD recollection interface will be collected in JPEG film transmission to the SD small discern, micro-controller can in addition save any other written knowledge required. Moreover, SSD1922 performance for a type of food items to give two-dimensional graphics acceleration roles, for instance virtual show clearly, photograph show clearly, present reporting, hardware cursor show clearly, line draw, obstruct convey bit raster performance, shade of color top up, shade of color expansion and so on. Built-in 256KB SRAM support animation and JPEG graphics. Supporting one of the greatest 640 480 delta procedure (200K) and 480 RGB 272 contrasting band pixel procedure (255K). Video input and the show clearly perseverance does not perpetually correspond to 1:1. Adjust the amount with SSD1922 aspects a built-in photograph storage to the amount of SRAM ascending before. Therefore, divergent perseverance, NTSC / PAL video source can be shown clearly on the LCD screen.
In short, Solomon Systech’s SSD1922 is a appropriate audio-visual yield in the request for paid job of a drive vehicle of the piece, which aspects expensive and not hard request for paid job create will sanction us to accelerate the introduction of new products.
